Differential Diagnosis of Cesarean Scar Pregnancies and Other Pregnancies Implanted in the Lower Uterus by Ultrasound Parameters

Figure 5

A 29-year-old female (gravida 2, para 1) presented with amenorrhea for 44 days. (a) The sagittal grayscale image showed that the sac was implanted in the lower endometrial cavity, protruding into the scar. A small amount of fluid was seen around the posterior of the conceptus, suggesting that the sac was implanted into the scar. (b) The color Doppler image showed the trophoblastic blood flow surrounding the sac, which made it difficult to estimate the source of the trophoblastic blood. Chorionic villi were visible within the scar with a laparoscopy combined with uterine artery embolization.
